Abstract
Separation of isotopes from a gaseous mixture of substances containing the isotopes by incorporating supplemental gas and adiabatically expanding at an expansion ratio and starting temperature to cool the mixture and effect condensation of at least a portion of the supplemental gas. Laser radiation is applied to effect selective excitation of one isotope component with selective retention of the non-excited isotope component in the condensate. The condensation may be accelerated by generating condensation nuclei. A compression joint may be used to effect a temperature rise of the gaseous mixture and peelers employed to separate the gas stream portion rich in excited isotope component from the portion rich in non-excited isotope component.
